Description

The TNS Listener, as used in Oracle Database 11g 11.1.0.7, 11.2.0.2, and 11.2.0.3, and 10g 10.2.0.3, 10.2.0.4, and 10.2.0.5, as used in Oracle Fusion Middleware, Enterprise Manager, E-Business Suite, and possibly other products, allows remote attackers to execute arbitrary database commands by performing a remote registration of a database (1) instance or (2) service name that already exists, then conducting a man-in-the-middle (MITM) attack to hijack database connections, aka "TNS Poison."

Detection & mitigation playbook

Vulnerability

  1. Detect

    Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).

  2. Remediation status

    No fixed release is recorded for CVE-2012-1675 yet. Track the upstream advisory, and apply the exposure-reduction steps below in the meantime.

  3. Mitigate without a patch

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
